M2당 코르텐 클래딩 비용
The rust on 코르텐 강철 클래딩 does not continuously fall off. While there may be some loose rust during the early oxidation stage, it eventually forms a 안정적인, tightly bonded patina. This is the key feature that gives Corten steel its long-lasting durability and low maintenance, making it a reliable choice for exterior cladding applications.
- 설명
평가할 때 코르텐 강철 클래딩, one common concern is whether the rust layer will fall off or stain surrounding areas. The answer depends on the stage of oxidation and environmental conditions.
Does Corten Steel Rust Fall Off?
Short Answer
-
초기 단계: 예, some loose rust may appear and can wash off
-
안정된 무대: 아니요, the rust layer becomes dense and firmly bonded, 그리고 벗겨지지 않는다
Why Rust Behavior Changes
1. Early Oxidation Stage
When Corten steel is newly installed:
-
녹층은 loose and porous
-
Rainwater may carry rust particles, causing runoff stains
-
Surface color is bright orange and uneven
This stage is temporary and part of the natural weathering process.
2. Patina Formation Stage
노출이 계속되면서:
-
다음과 같은 합금 원소 구리, Cr, 그리고 니 modify the rust structure
-
The oxide layer becomes compact and adherent
-
The surface transitions to reddish-brown
At this point, the rust layer acts as a 보호 장벽.
3. Stable Stage
After full weathering:
-
Rust is firmly attached to the steel surface
-
No flaking or peeling like ordinary carbon steel
-
Minimal or no runoff under normal conditions
Comparison with Ordinary Steel
| 측면 | 코르텐 스틸 | Ordinary Steel |
|---|---|---|
| Rust structure | 조밀하고 안정적 | Loose and flaky |
| 부착 | 강한 | 약한 |
| Flaking | Minimal after stabilization | Continuous |
| Protection | Self-protecting | Corrosion continues |
Factors That Affect Rust Stability
-
Environment: Alternating wet and dry conditions help form a stable patina
-
Water drainage: Poor drainage may prolong the loose rust stage
-
표면 준비: Pre-weathered steel reduces runoff issues
-
Installation design: Avoid constant water accumulation
Practical Considerations
-
Initial runoff may occur in the first weeks to months
-
미리 녹슬었던 (미리 풍화된) Corten steel can minimize staining
-
Proper design (drip edges, spacing) helps control water flow
